CASTING Application filed December To tr/107mm if; may concern:

lie it known that l, Louis E. LnrnNs, a citizen of the United States,Aresiding at `Vicksburg, in the county of Tarifen and Stato ofbilississippi, have invented ,certain new and useful lniproven'ients inCasting l\z[achines, of which the following is a full, clear, concise,4and exact description, reference being' `had to the` accompanyingdravvings, forming a kpart of this specification.

My invention relates to improvements in casting machines,` and is4particularly concerned With the provision of a novel casting machinefor casting, stereotypes.`

The objects of my invention are- First: Toproduce a castingfmachine formaking stereotypes from t-he `conventional matrix or man which is simplein construction, economical to manufacture, and easy to operate; i

Second.: To provide a .casting machine of the character' described forcasting stereotypes designed x particularly for use upon cylinder.printing machines:

Third: To provide a. casting machine for casting `stereotypes for.. useupon cylinder printing machines in Whichfthe cylinders are provided withlongitudinally,extending slots for anchoring. ,the printing. ch aractersg Fourth: To provide acasting machine which can be used With. mats ofdifferent sizes, and V Fifth: To providea casting machine such asdescribed comprising means for forming depressed margins around theprinting. face of the stereotype for receiving the usual clampingvdevicesfor securing stereotypes to cylinder' printing machines.

Other objects will appear as `this description progresses, referencebeing had tothe accompany-ing1 drawings in which lzligure` 1 is a. planview of my improved casting machine, portions thereof f being brokenaway for .the purpose of better illustration,

section shown in Figure4 but showing a modified form of my invention.

Throughout the several views, similar reference characters are used for.referringto similar parts, and the sections are taken looking in thedirection of the small arrovvs.

The embodiment of-myinvention which I have illustrated comprises aidragmember 10 having a concave.cylindrical .casting surface, and a copemember' 11 having ,aconvex cylindrical casting surface. At one|= end,the drag member 10 is provided with .tivospaced projecting lugs 155 andv13, and the copemember 11 `is provided` with a third projecting lug 14which entends between the tivo lugs., 12 and 13 of EtheV drag member(see Figure 1). A pintle 15 passing through the lugs .12, 13 and 14provides a, pivot pin upon which the cope member can lbe turned for apurpose which will be. referred` to later, on. The ,lug 14 has anfextension v16, whiclris adapted. to engage the rear sideof the lug 17,which projects downwardly fromwthe drag member `10 to limit theopeningmovement of the cope member relatively` to the drag member.

The drag. member is providedwvith legs 18 for support-ingv thecastingniachine in a horizontal position. A stud 119 projectingrearwardly fromY the lug 17` and `studs 2O projecting vreai'ivardly fromthe upperportionf of the cope member provide a vsecond set ofv legs for.supporting the castingmachinein a vertical position, as will be pointedout later on. in this description.

A bar 21 extending between the yopposite sides of the coge memberre-inforces the rear end of this member, and a flange 22 eX- tendingaround the rear .end of the convex surface of the cope memberserVes topropg erly space this end ofv the, cope member from the drag member.-BossesQS extending inwardly from the convex .surface of the oppositeend. of the cope member perform a. similar function.

For clamping thecope member to the .drag member, I provi deva bracket24, at each side of the forward .end of the dragmember. These bracketscan be formed integrally With the drag member, or formed separately andsecured thereto by means of screws-,25. A link 26 has one of its endspivotally mounted upon each of the brackets 26 by means of a screw 27passingthrough a .suitable `bore in the end of the linkandinto thebracket properly position the mats.

24. A. screw 28 is mounted in the free end of each link 26. The upperend of the screw 28 is provided with a cross pin 29 for rotating it.Each side oit the cope member adjacent its front end is built up, asshown at 30, to provide a seat for the inner end of the screw 28.

With the construction just described, all that is necessary to do, tosecure the cope and drag member together, is to turn the links 26 to theposition shown in Figure l, and turn the screws inwardly until the innerends engage the seats 30 and securely clamp the cope to the drag member.will, ot course, be understood that the cope member is released from thedrag member by a reverse operation.

The .mats from which stereotypes are cast are made in many differentways, and usually have depressed portions attheir edges indicatingmargins. To make a stereotype from such 'a mat with my improved castingmachine, the mat is placed on the drag member, as shown in Figure 1,preferably witlrits longitudinal center substantially coinciding withthe longitudinal center of .the drag member which, it desired, can beindicated by a mark 31. Other similar marks 31 can be made in thesurface of the drag: member to enable the operator to It desired,indicia such as indicated at 32 can also be used to assist the operator.

To hold the mats in the proper positions, I provide a transverselyextending margin strip 33 which is curved to conform to the curvaturesof the cope and drag members, and is also provided at its rear edge withlugs 34 which are received by the transversely extending grooves 35formed in the concave surface of the drag member. By this means the matcan be held so thatits outer end will be positioned adjacent the outerend ot the two casting members. as shown in Figure 1. For holding` thesides of the mat, I provide the two longitudinally extending marginstrips 36, the sides ot which, adjacent the cope, arel shouldered asindicated. at 37 (see Figures .Sand 6) to provide longitudinallyextending recesses for receiving` the side edges of the mat.

Y To make it possible for the operator to adjust the margin strips 36tov differentsized mats, I provide suitable clamps. each `comprising abody member 38 which is slidably 4mounted upon an annular Y rail 35)formed at the front end of the drag member, and each having alongitudinally extending groove 40 formed therein through which themargin strip 36 yin slide. A clamping .plate 41 has one edge 42 turnedinwardly to engage with the. margin strip 36 and is provided with anopening through which the stud screw 43 projects. A washer 44 and a nut45 provide means for clamp-V ing the down turned edge l2 ot the clamping plate 41 against the margin strip. set screw 46 provides means forholdingr the clamp in any desired position on the rail 39.

In the drawings, margin strips 353 and $16 are shown holding a mat 4T inposition adjacent the outer ends ot the casting members.

The outer end ot the drag member 10 is provided with a gate 4S fordirecting the type metal into the space between the two casting members.

there my improved casting` nuufhine is used for casting stereotypes torcylinder '1 machines in which the cylinders are provided withlongitudinally extending slots t'or anchoring the printing characters. lprefer to provide the cope member 1l. with the longitudinally extendinggroove 49 which opens through its convex surface. The longitudinallyextending rib 49 re-inforces the cope member immediately adjacent thegroove 49. To prevent metal from flowing down this groove further thanthe limits of the mat, I provide the margin strip 38 with the upwardlyextending lng 50, which fits into the groove 49.

A handle 51 is secured to the cope member by the two brackets 52, one ofwhich is secured to each side of the cope member.

In the use of my improved casting machine, it is placed in a horizontalposition, as shown in Figure 2, and the cope member is raised to a pointpast the vertical position where itis supported by the projection 16comingr into coni act with the. lng 1T. The mat is then secured. inposition by means of the margin strips, as shown in. Figure 1.v the twomargin strips 36 prefs erably being arranged so as to bring thelongitudinal center ot the mat substantially in line with the centerline 81 of the dragr member. The cope member is then turned over on thedrag member and secured by means oi the clamps comprising the links 26and the screws 28. The operator then seizes the .handle 51 and lifts themachine to a vertical position in which it will be supported by the legs19 and 20. The molten type metal is then poured into the gate 48, andpasses down between the mat and the cope member.

The casting machine can then be replaced in its horizontal position` theclamps anfastened, and the cope member separated from the drag member.The stereotype can then be removed trom the cope member to which it willordinarily adhere on account of the projecting rib ot metal which iscast in the groove 49. It is an easy matter to remove the stereotypefrom the cope member.

In Figure 7, I have illustrated a modified form of my invention in whichthe grooves 35 are omitted from the drag member, and

the adjustment of the margin strip 33 is provided'by means of a screw 55which projects outwardly t'rom the margin strip adjacent one end thereofand through a longitudinally extending slot 56 formed in one e-dioe ofthe drag member. A wing nut 5T provides means for securing the marginstrip 33 in any ot its adjusted positions.

1While I have described the details o'tconstructionotf the preferreden'ibodiment ot my invention, it is to be clearly understood that myinvention is not limited to these details but is capable ot otheradaptations and modifications within the scope ot the pended claims, andit is to be jiarticularly understood that my casting machine is notlimited to the production ot cylindrical stereotypes, but is capable otproducing tlat stereotypes.
